Abstract

A mathematical model is developed by coupling the electrochemical equation, the energy equation and the resistive network model to find the temperature behaviour of the battery in electric vehicles. The model is applied for a common battery pack in the battery industry under Japanese 1015 Mode EV driving cycle. Simulation results indicate that the maximum temperature for the battery pack occurs at the maximum discharge rate where the heat generation rate is very high. The simulation results also show that the portion of the heat conduction in heat dissipation can be increased by reducing the heat conduction resistance of the casing material and thus the effect of the heat conduction on temperature behaviour of the battery pack cannot be neglected.
